I don't know anything specific about the Natural but just going on general stuff...

How susceptable to weather the bow would be would depend entirely on how well thebowis sealed. I really don't think I'd take a non-glass bow out in wet weather, just in case.

String follow depends a lot on how well the bow is tillered and how well it's designed for the shooter's draw length. A bow that's designed for a shooter with a 26" draw will show string follow if someone with a 30" draw shoots it. Might even break.

It'd be a good idea to try and get hold of Schulz directly and ask him specifics about it. Heck, I don't even know if he's still alive. [:-]
